JavaScript toLowerCase Example
The following set of examples helps you understand the toLowerCase Function.
The second JavaScript statement, Str3, converts the above-declared Str1 string into lowercase.
Instead of declaring and assigning the string, we can also use the function on a string literal directly. The folding two lines for Str4 and Str5 use the same.
<!DOCTYPE html> <html> <head> <title> JavaScriptToLowerCase </title> </head> <body> <h1> JavaScriptToLowerCase </h1> <script> var Str1 = "Learn JavaScript at Tutorial Gateway"; var Str3 = Str1.toLowerCase(); var Str4 = "Hi, This is FROM JS".toLowerCase(); var Str5 = "JAVASCRIPT LOWERCASE".toLowerCase(); document.write("<b> Lowercase Letters are:</b> " + Str3); document.write("<br \> <b> Lowercase Letters are: </b> " + Str4); document.write("<br \> <b> Lowercase Letters are: </b> " + Str5); </script> </body> </html>
